i 5 H G Patented Jan. 14, 1930 UNITED STATES JOHN CBOOKSHANKS, OF GLASGOW, SCOTLAND HEEL FOR roorwEAR Application filed October 25, 1926, Serial No. 144,096, and in Great Britain December 1 1925.

This invention relates to improvements in and connected with footwear, and refers to that class by which a worn part of the heel can be readily removed and a t fresh wearing piece inserted at any time as may be desired, and thereby avoiding the necessity of having so frequently to repair the heel.

In carrying out this invention, 1 provide a plate of steel, aluminum orother suitable metal, havinga short grooved-part at each side of theinner part thereof and with a ridge at the extreme inner end of the plate which connects the two grooved-parts to gether. I also provide a small ridge or clip at the outer edge of the plate, holes being also provided for the attachment of the plate to the heel of the shoe.

I also provide a pad of rubber, leather or other suitable material with a groove of similar dimensions to the grooved part formed on the plate so that, when the pad is placed in position, the grooves on each engage with each other and the small ridge engages with a recess on the outer end of heel, thereby locking the plate and the pad together.

Theplate may also be wholly or partially embedded in the heel and may also cover the whole heel or part only.

In order that this invention may be properly understood and readily carried into effeet, I have hereunto appended two sheets of drawings, of which Figure 1 is a side view of the metal plate as applied to a gentlemans heel.

Figure 2 is a side view of the pad.

Figure 24; is a sectional view showing a slightly modified form of ridge in plate. .Figures 25 and .26 are plan and side views of single and double horse shoe clip.

Referring to Figures 1 to 6 of the" drawings, A is the metal platehaving the short grooved-part B oneach side of the inner end of the plate B, formed by bending over the sidesof the plate and with a ridge Get the extreme inner endrof the plate B connecting the two groovediparts together, or the plate B may be formed with the ridge C, as shown in Figure 24. At theouter end of the plate 13, there is a small ridge orcatch D. E are suitable holes by which the plate is attached to theheel F of the shoe. G is :the pad of rubber, leather or other suitable material having a groove H equal in dimension "to that of the grooved part B in the plate A at the extreme inner end of the pad G. I is a recess on the inner end o-fthepad G for the reception ofthe ridge G on the plate A. J is a recess on theiextreme outer .end ofthe pad'for the engagement of the ridge D on the plate A. The pad G is inserted from the outer'end of the heel to wards the inner and when in position becomes locked with the plate A against longitudinal movement by the engagement of the ridges C and D with the recesses I and J, and against lateral movement by the grooves B and recesses H. When the pad is being inserted, it

is sprung over the ridge D and when to be removed, the reverse action takes place. This construction admits of a cushion pad which is of substantially equal thickness throughout its length and width, and a pad which not only is free to be compressed throughout its thickness toward the rear end of the heel, but which also presents the full thickness of the pad for wear at the back of the heel.

The pad G may also, if desired, be attached to the heel F by screws passing through the holes or openings K. A suitable screw or screws is or are provided for attachment of the pad to the heel of the boot or shoe.

Referring to Figures 7 and 15, the metal plate is embedded in the heel F and does not cover the whole surface of the heel, different forms of heel being shown.

Referring to Figures 8, 9, 10, 11, 12 and 13, the plate A is so formed that, when the pad G is inserted into position, the back portion of the plate A becomes embedded in the pad G through the recess L formed in the pad and becomes locked in the manner herein before described. In'these figures no ridges are shown, although they can be applied, if desired.

Referring to Figure 14, the whole area of the heel F is covered by the plate A.

Referring to Figures 16, 17 and 18, the metal plate A is so pierced as to form on the opposite end a small projection M like a tooth on a rasp which, when the pad G is inserted, engages with a slot or slots N in the pad A, thereby preventing any back slip and thus effecting a better and more secure grip of the pad G to the plate A. This may be applied to all the different forms described, if desired.

Referring to Figures 19, 20 and 21, the metal plate A is smaller in area than the base of the heel F and when in position no part of the plate A is exposed.

Referring to Figures 22, 23, 25 and 26 the ridge or clip D on the extreme outer end of the plate A is of horse-shoe clip formation and engages with the recess J in the pad G. The clip D is bent over into U-shaped form and when the plate A is placed in position, this U-part engages, as stated, With the recess J in the pads. A double U-part may be used to effect a better hold.

It is to be understood-where parts are referred to in some of the figures and not in others, such as the clips or ridges for effecting greater security of attachment of the pad to the plate these are equally applicable to all forms of heels, both ladies and gentlemens.

Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is A detachable heel comprising a fixed plate for permanent attachment to the bottom of a heel and having at its forward corner portions depending inturned flanges disposed substantially in parallel relation to each other and extending rearwardly not more than half the length of the plate, and a pad adapted to be detachably mounted on the plate and having grooves in its opposite sides and at its forward corner portions opening through the forward end of the pad to receive the flanges of the plate by a forward sliding movement of the pad, said grooves being substantially the length of the flanges to provide stop shoulders on the pad limiting the forward sliding movement thereof and leaving the rear portion of the pad intact, and means for holding the pad from sliding backwardly when in place.

In witness whereof I aflix my signature.

JOHN CROOKSHANKS.
